1. The problem statement, all variables and given/known data For the element shown below, v(t) = ½ t Volts and i(t) = 12t-4t2 Amps. a)Find the instantaneous power p(t) as a function of time. b)Find the energy supplied (this value can be negative or positive for each range) to the element for the following three time ranges: 0 < t < 3, 3 < t < 4, 0 < t < 4, those are less than or equal to. 2. Relevant equations There is a picture of the circuit that show that it satisfies the Passive Sign Convention. P(t) = V(t) i(t) w= the integral of P(t) 3. The attempt at a solution for part a. I multiplied the given V times the i and found p(t) to = 6t^2 - 2t^3 watts. for part b. I attempted to take the integral of P(t) from the first point listed; 0 < t < 3 I dont understand the integration. Do i integrate from infinitie to 0, then from 0 to 3, and then from 3 to infinitie?? im so lost at this point.
